IEQ Investigation Process

Identify deficiencies that may impact IEQ and/or sources of odor concerns. Typically includes the following depending on the nature of concern, but not limited to:

  • interview/questionnaire of concern individual(s)
  • inspection above drop ceiling (condition of roof deck, pipe insulation, return air plenum)
  • inspection of ventilation system (operation of variable air volume box and outdoor air dampers, check controls, measurements of carbon dioxide, temperature and relative humidity, sources near outdoor air intake, measure return and supply air volume, cleanliness of coils, liner and condensate pan)
  • inspection of exterior
  • inspection below drop ceiling (housekeeping, sink and floor drain traps, signs of past and present moisture concern via visual and/or moisture meter, mold growth, ensure connection of current and capping of abandoned sanitary vents, odorizers, excessive plants and fabric items, identify potential pathways, and measure volatile organic compounds, carbon monoxide, and lighting)

Date of Assessment(s): December 9, 2019

Mold growth was observed on both sides of a gymnastics mat. The mat was reported to be on the bottom of a stack of mats.

The mold growth appeared in a formation that resembled drip marks. This formation is an indication that the mat may have been put away wet, perhaps after cleaning.

Other mats were located within the storage room. The Office of the Environment inspected a representative sample of the other mats. No additional mold growth was identified. 

The impacted mat was cleaned onsite, however a strong musty odor remained.

Corrective Actions
